NOTE: When connecting the Optocoupler Supply, it is recommended

that you do not use MForce Power Ground as Ground as this will defeat the optical isolation.

Optocoupler Reference

The Microstepping MForce PowerDrive Logic Inputs are optically isolated to prevent electrical noise being coupled into the inputs and causing erratic operation.

There are two ways that the Optocoupler Reference will be connected depending whether the Inputs are to be configured as sinking or sourcing.
